Correlates of heavy smoking (greater than or equal to 25 cigarettes per day) were examined in a group of 380 smokers participating in a minimal-contact smoking relapse prevention trial. The results indicate that heavy smokers are more dependent on cigarettes. Compared with smokers consuming 15 or fewer cigarettes per day, heavy smokers reported greater difficulty quitting, were more troubled by...

Background: Epididymal spermatozoa have been used for production of offspring from genetically important animals after they are dead. To attain optimal fertility with epididymal spermatozoa, they should be preserved in a suitable medium in 37°C. Preservation media provides requirement for spermatozoa and affects its motility, viability, and fertility. Sucrose is one of the important components ...

Position changes are believed to increase the efficacy of phototherapy and this practice is routinely used in all neonatal departments in our country. The aim of this study was to determine the effect of routine turning on the total serum bilirubin (TSB) concentration versus only supine position. In a randomized clinical trial fifty healthy term jaundiced neonates who were admitted to the ...

The aim of this investigation was to monitor metronidazole concentrations in the gingival crevicular fluid (GCF) collected from periodontal pockets of dogs after treatment with an experimental 15% metronidazole gel. Five dogs had periodontitis induced by cotton ligatures placed subgingivally and maintained for a 30-day period. After the induction period, only pockets with 4 mm or deeper receive...

Patients undergoing a lateral thoracotomy for pulmonary resection have moderate to severe pain postoperatively that is often treated with opioids. Opioid side effects such as respiratory depression can be devastating in patients with already compromised respiratory function. This prospective double-blinded clinical trial examined the analgesic effects and safety of a dexmedetomidine infusion fo...

This work investigated the toxicity of inorganic mercury and zinc preventive effects in female rats sacrificed 12 or 48 h after HgCl2 exposure. Female Wistar rats were subcutaneously injected with ZnCl2 (27 mg/kg) or saline (0.9 %), and 24 h later they were exposed to HgCl2 (5 mg/kg) or saline (0.9 %). Rats sacrificed 12 hours after Hg administration presented an increase in kidney weight and a...
